  • What is DBP used for?
  • Production has been steadily decreasing during the 1990’s. Over 75% of DBP is used as a plasticizer in polymers such as PVC, 14% is used in adhesives, 7% in printing inks and 3% in other miscellaneous uses, including sealants and grouting agents used in construction as well as consumer products such as cosmetics.
  • How does DBP affect the environment?
  • These results indicate that DBP contamination accelerates carbon metabolism, which makes more carbon in soil converted to CO 2 and methane, causing loss of soil carbon pool, while inhibiting carbon flux from the atmosphere to soil, exacerbating the greenhouse effect and negatively affecting the environment.
  • How many producers of DBP are there in the EU?
  • There are currently 3 producers of DBP in the European Union. The estimated production in the European Union was around 26 000 tonnes in 1998, over two-thirds of which was used in the EU. Production has been steadily decreasing during the 1990’s.
  • What is dibutyl phthalate (DBP)?
  • Among them, dibutyl phthalate (DBP) is one of the top PAEs in terms of usage (Cheng et al., 2019a). As DBP and plastic polymers are linked by unstable chemical bonds (e.g., hydrogen bonds), it is easy to escape from plastics to the natural environment (Zhang et al., 2015).
  • What are DBP concentrations in vegetable greenhouses and agricultural soils?
  • The DBP concentrations were detected in vegetable greenhouses and agricultural soils in the Shandong Peninsula, China, ranging from 0.02 to 15.72 mg kg −1 and ND (not detected) to 9.86 mg kg −1, respectively (Chai et al., 2014; Li et al., 2016).
  • Does DBP affect soil microorganisms in the Yellow River Delta?
  • Therefore, in this study, a typical salinized soil (agricultural soil in the Yellow River Delta) was selected and treated with DBP at different doses (1.0, 10, and 50 mg kg −1) and incubated for 30 d. The results revealed that DBP exposure significantly decreased the abundance of soil microorganisms.
